INyanga ngowona mzimba wesibhakabhaka ukufutshane noMhlaba, kwaye idlala indima enkulu ekwenzeni ubomi bubekho kuwo, ngenxa yomxhuzulane wawo, omisa ukujikeleza koMhlaba kwi-axis yawo, kwaye oku kukhokelela kuzinzo lwemozulu. Inyanga ijikeleza uMhlaba kwindlela ye-elliptical, ukuze i-apogee ibe yi-405,696 km, eyona ndawo ikude kakhulu yenyanga ukusuka eMhlabeni. Xa inyanga isondela emhlabeni, ikumgama weekhilomitha ezingama-363,104, kwaye le ndawo ibizwa ngokuba yi-perigee. Oku kuthetha ukuba umgama ophakathi koMhlaba neNyanga yi-384,400 km.
Amandla omtsalane phakathi kweNyanga noMhlaba akhiwe ngokomthetho kaNewton wokuxhuzula umhlaba wonke, nto leyo ebonisa ukuba amandla okutsalana phakathi kwayo nayiphi na imizimba emibini kwindalo iphela ilingana ngokuthe ngqo nemveliso yobuninzi bazo, yaye ngokunxamnye nomlinganiselo wesikwere. umgama phakathi kwabo. Kwaye siyaqaphela amandla omtsalane wenyanga eMhlabeni ngokucacileyo kwizinto ezimbini zamaza emanzini olwandle kunye neelwandle. Bekuya kwenzeka ntoni ukuba umgama ophakathi kwenyanga nomhlaba ubunokuncipha?
Kukho iziganeko ezininzi ezingaqhelekanga eziza kwenzeka, kwaye apha sibeka iimeko ezisondeleyo ezisekelwe kwisiseko sesayensi. Umtsalane wenyanga emhlabeni uya kwanda njengoko umgama ophakathi kwawo uncipha, njengoko usitsho umthetho kaNewton womxhuzulane okwindalo iphela. Ukuba inyanga isondele kakhulu, amaza aya kwanda ngokumangalisayo, nto leyo eya kukhokelela kwizikhukula ezinkulu zehlabathi. Oku kuthetha ukunyamalala kwezixeko ezininzi phantsi kwamanzi. Umhlaba ngokwawo uya kuchaphazeleka ngulo mxhuzulane owomeleleyo, ngempembelelo yawo kuqweqwe lwangaphandle loMhlaba okanye ingubo, ukuze uphakame kwaye uwe. Ngenxa yale ntshukumo, umsebenzi wetectonic uya kwanda kwaye iinyikima ezimbi kakhulu kunye neentaba-mlilo ziya kwenzeka.
Ukusondela kwenyanga emhlabeni kuya kwandisa isantya sokujikeleza komhlaba kwi-axis yawo, ngokomthetho wolondolozo lwesantya se-angular. Ngeli xesha, iinkanyamba ziya kuveliswa ngenxa yokujikeleza ngokukhawuleza kwe-atmosfera. Kwaye imini eMhlabeni iya kuba mfutshane.
Kumbukeli, inyanga iya kubonakala inkulu ngokusondeleyo kuMhlaba, nto leyo eya kuba negalelo ekuthinteleni imitha yelanga. Ngaloo ndlela, ukusithwa kwelanga yinyanga kuya kuba yinto eqhelekileyo.
Yaye ukuba inyanga isondela kufutshane, ize ifikelele koko kwaziwa ngokuba yi “Roche limit” (umgama apho umzimba wesibhakabhaka uhlala ubambene ngomxhuzulane wawo xa usondela komnye umzimba), inyanga iya kuqhekeka ize iphuke ngenxa yamandla olwandle aphumela ngaphandle. ukusuka kubunzima beplanethi. Ezi nxalenye eziqhekezayo ziya kwenza amakhonkco eMhlabeni, njengalawo eSaturn. Nangona kunjalo, akuyi kuthatha ixesha elide ngaphambi kokuba ezi ndawo ziwele eMhlabeni njengamawaka e-asteroids.
Enyanisweni, kummandla wethu wezijikelezi-langa kuye kwenzeka into efanayo nale ntlekele. Ngomnyaka ka 1992 i-comet Shoemaker-Levy 9) yasondela kuJupiter yagqitha kumda weRoche kaJupiter, yaza yaqhekeka yaziingceba ezingaphaya kwamashumi amabini, ezaqala ukuyijikeleza, zaza zawa enye emva kwenye kuJupiter ngo-9 AD. Amandla ayo okutshabalalisa ayeqikelelwa kwiibhombu zeathom ezizizigidi ezingama-1994!
Ngaloo ndlela, kuyacaca ukuba iziphumo zemeko enokwenzeka xa inyanga isondela emhlabeni iya kuba yintlekele kakhulu. Esi siphelo sibuhlungu siphembelele eminye imisebenzi ye-dystopia kunye ne-apocalypse. Kodwa eneneni, iNyanga isuka eMhlabeni nge-3.8 cm ngonyaka. Ngoko ke, akunakwenzeka ukuba uchungechunge lweziganeko eziqikelelwayo ezifana neenyikima, iintaba-mlilo, kunye nezivunguvungu ezilandelelanayo ziya kwenzeka, kwaye asiyi kungqina ukukhanya kwesigxina, kwaye akuyi kubakho iindandatho ezifana neendandatho zeSaturn, kwaye iNyanga iya kuhlala. umba wokhuseleko nozinzo lweplanethi.
